[Linux] A compiler with support for C++17 language features is required. 에러 발생시 조치방법

Centos 7환경에서 pdns 컴파일 중 에러가 발생했다.

[root@sysops pdns-4.5.2]# ./configure 
checking whether g++ supports C++17 features with -std=c++17... no
checking whether g++ supports C++17 features with +std=c++17... no
checking whether g++ supports C++17 features with -h std=c++17... no
checking whether g++ supports C++17 features with -std=c++1z... no
checking whether g++ supports C++17 features with +std=c++1z... no
checking whether g++ supports C++17 features with -h std=c++1z... no
configure: error: *** A compiler with support for C++17 language features is required.

해결방법으론 gcc-c++ 패키지를 설치해준다. 

[root@sysops pdns-4.5.2]# yum install gcc-c++

 

만약 이미 설치되어있으나 gcc 버전이 낮다면 devtoolset-8 등을 설치해준다.

yum install centos-release-scl
yum-config-manager --enable rhel-server-rhscl-7-rpms
yum install devtoolset-8
scl enable devtoolset-8 bash
